In complex environments, traditional industrial robot control systems can no longer meet the automation production requirements of industrial parts handling tasks. Therefore, the research aims to construct an industrial robot sorting and assembly control system based on Ethernet bus. The innovation lies in deeply coupling Profinet real-time Ethernet with self-tuning fuzzy PID control, compressing communication jitter to sub millisecond level; Introducing a greedy visual hybrid algorithm; A four layer integrated framework of "hardware communication algorithm human-machine" has been constructed, which can directly reuse existing Siemens PLC and I/O ecosystems, significantly reducing deployment costs. Experimental results show that when the fusion control algorithm's time is 4.0s, the position tracking deviation is 0.012mm. The position tracking deviation for the deep deterministic policy gradient algorithm is 0.018mm, which is worse than the fusion algorithm. The sorting recall rate for the fuzzy sliding mode industrial sorting and assembly control system is 93.67%, which is lower than that of the fusion control system. The above research results provide a replicable technological paradigm for the next generation of highly flexible and scalable intelligent production lines, and are expected to be quickly implemented in scenarios such as micro nano electronic assembly, flexible pharmaceutical manufacturing, and circular remanufacturing.
